Hi,
I have recently acquired a Soundcraft SAC200 and am looking at connecting this to marlist to do fader starts. Now this seems pretty simple but just want to check I’m not missing anything here.
Each fader has a 9 pin logic out for external control with the pin diagram as below:
1 = Logic GND
2 = On Access (Input B selected)
3 = + 7.5v
4= On Access (Input A selected)
5 = CUE Enable Acsess
6 = Logic GND
7 = N/C
8 = + 7.5v
9 = N/C
an RS232 COM Serial to USB hub is probably not the correct device for your needs. The Pinout of the Soundcraft console suggests it’s a GPI port rather than serial - to use those with mAirlist, devices like the I/O Warrior are better suited.
Would it be possible then to wire to a game port as in Charlie Davy’s example posted on this forum ? If so would i wire from the Access On pin or via the + 7.5v
No, it is not possible to wire up a logic GPI port to a game port! Well, not unless you want to risk frying the PC and possibly the Soundcraft as well. Charlie’s game port wiring example only applies to (usually older) desks where the channels use a simple contact closure which is often simply wired in parallel with the equivalent switch on the channel and not a full-blown logic interface like the one on the Soundcraft SAC200.
That is why you do need to use an IO-Warrior or similar device which is designed to use logic signals. Trying to bodge up some ‘cheap and cheerful’ alternative will at best, just not work; and at worst, as I’ve said, it will cause expensive damage. At least you can’t say we didn’t warn you!
